SPECIFICATION forming part of Letters Patent No. 371,825, dated October 18, 1887.

Application filed May 10, 1887. 7

State, have invented certain new and useful Improvements in Vehicle-Springs; and we do hereby declare that the following is a full, clear, and exact description thereof.

Ourinvention relates to vehicle-springs; and it consists in certain peculiarities of construction and combination ofparts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed. In the drawings, Figure 1 represents a side elevation, partly in section, of our vehiclespring in position 011 a wagon-bolster; Fig. 2, aplan view of a portion thereof, and Fig. 3 a detail perspective view of a clamping-bolt.

Referring by letter to the drawings, A rep resents a bar, to the ends of which, upon the under side thereof, are secured rub'plates B, and centrally secured to said under side of the bar is another plate, C, preferably provided with a concave depression, a. Passed through the extremities of bar A and slots 1) in the ends of a semi-elliptic spring-section, D, are bolts E, that have cross-heads c. The crossheads c of the bolts E bear upon the springseotion D 0 and have their ends (I bent at right angles to come over against the edges of said spring-section and bear upon the rub-plates B. Riveted or otherwise suitably secured to the ends of the spring-section D adjacent to the slots b there- 5 in are recessed lugs F, in which are fitted rubber or other suitable buffers, G. Bolted or otherwise suitably secured to the springsection D is another semi-elliptic spring'section, D, having its ends provided with slots 0 b and recessed lugs F, and in the latter are fitted rubber or other suitable buffers, G. The slotted ends of the springsection D are secured to a vehicle-bolster, H, by means of bolts E, similar to the ones E above described, and fast 5 to the ends of the bolster upon its upper side are rub-plates 13, while another plate, 0, is also fastened to the center of said bolster and provided with a concave depression, ct.

Interposed between the spring-sections D D are spiral springs I, that fit around and are Serial No. 237,671. (No model.)

held in place by the opposing lugs'FF on said spring sections. Centrally secured to andprojecting from opposite sides of the spring formed by the united sections D D are conical spiral springs J J", the free ends of which impinge against the concavities a a in the plates 0 0 when more than ordinary strain comes upon said spring, thereby increasing the resistance to such strain.

We have shown our spring as secured to the 6:) bolster of an ordinary wagon, and consequently recessed the ends of bar A to fit the standards K on said bolster; but it will be understood that the spring is applicable to any style of vehicle, and in some instances the recesses in' 6 the ends of said bar may be omitted.

\Vhile we have shown and described the two spring-sections D D, it is obvious that for a light spring we may omit the former section and bolt the latter to the center of bar Awithout departing from the spirit of our invention.

By the construction above described we pro Vide an extremely simple spring that can be readily manufactured at a comparatively low cost, and which is vnot only applicable to the vehicle-body,but may also be utilized as a seatspring on some styles of vehicles.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. V A vehicle-spring comp rising at bar, a continuous semi-elliptic spring-section having slotted ends, suitable bolts for-securing the ends of the spring'seetion to the vehicle-bolster, and spiral springs interposed between said ends of 8 5 the spring'section and those of the bar, substantially as set forth.

2. A vehicle-sp ring comprising a bar, a continuous semi-elliptic spring-section having slotted en ds, suitable bolts for seou ring the ends 0 of the spring-section to a vehicle-bolster, spiral springs interposed between said ends of the spring-section and those of the bar, and. an intermediate spiral spring secured to said springseetion, substantially as set forth.

3. A vehicle spring comprising a bar, two oppositely arranged and centrally united springsections having slotted ends, suitable bolts passed through the slots to loosely eonnect the springsections with the bar and a vehicle-bolster, and spiral springs interposed between the opposing ends of said spring-sections, substantially as set forth.

4. A vehicle-spring comprising a bar, two oppositely-arranged and centrally-united semielliptic spring-sections having slotted ends, suitable bolts passed through the slots to loosely connect the spring-sections with the bar and a vehicle-bolster, spiral springs interposed between the ends of the spring-sections, and another spiral spring arranged to project from the center of each spring-section, substantially as set forth.

5. A vehicle-spring comprising a bar, two oppositely-arranged and centrally-united semielliptic spring-sections having slotted ends, and spiral sprin gsinterposed between the ends of the spring-sections, in combination with bolts provided with cross-heads having right-angular ends and passed through the slots in said springsections to secure the latter to the spring-bar and vehicle-bolster, substantially as set forth.

6. A vehicle-spring comprising a bar, two semi-elliptic spring-sections having slotted ends, lugs secured to the opposing sides of the spring-sections adjacent to the slots therein, and spiral springs having their ends fitted around'the lugs, in combination with suitable bolts passed through the slots in said springsections to secure the latter to the spring-bar and vehicle-bolster, substantially as set forth.

7. A vehicle-spring comprising a bar, two semi-elliptic spring sections having slotted ends, recessed lugs secured to the opposing sides of the springsections adjacent to the slots therein, buffers seated in the lugs, and spiral springs having their ends fitted around the lugs, in combination with suitable bolts passed through the slots in said spring-sections to secure the latter to the spring-bar and vehiclebolster, substantially as set forth.

8. A vehicle-spring comprising a bar having rub-plates secured to its ends upon the under side thereof, another plate centrally secured to said under side of the bar, and two oppositelyarranged and centrally-united semi-elliptic spring-sections having slotted ends, in combi nation with a bolster having rubplates secured to its ends upon the upper side thereof, another plate centrally secured to said upper side of the bolster, spiral springs interposed between the ends of the spring-sections, a spiral spring arranged to project from the center of each spring-section, and suitable bolts connecting the respective spring-sections to the bar and bolster, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands, at Franksville, in the county of Racine and State of Wisconsin, in the presence of two witnesses.
